STANCHION.

Specification of Letters Patent.

latented Apr. 4, 1916.

Application led September 18, 1915. Serial No. 51,299.

To all whom t may concern.'

Be it known that I, Winnaar MITCHELL, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented new and useful Improvements in Stanchions, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specilication.

This invention relates to stanchions.

The invention is designed more particularly to provide a new and improved means for securing the lower portion of the stanchion' to the barn door.

-The invention is further designed to provide an anchoring device for connecting the lower portion of the stanchion with the barn floor which permits limited lengthwise movement of the lower end of the stanchion with respect to the stall, .which movement is resisted by springs.

rlhe invention further consists of the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof. Y

In the drawings Figure 1 is an elevation view of the device embodying the invention, showing it attached to the stanchion and stall; Fig. 2 is a section taken on line 2-2 of Fig. 1; Fig. 3 is a section taken on line 3 3 or Fig. 2.

The device is shown anchored in the ridge 4 of the concrete floor of the barn between the stall floor 5 and the trough-shaped depression 6 in front of the stall.

The device consists of a base member 7 anchored in the ridge Ll, a clip 8 pivotally secured to the lower end of the stanchion 9 which may be of any suitable construction, and means for connecting said clip to the base member 7. The base member 7 is made of one piece of metal forming an open boxlike structure having sides 10 and bottom 11 formed tby upwardly inclined portions 12 which permit any material falling into the connection to move down said portions and onto the barn floor. Integral lugs or feet 13 extend from the bottom below the same and are provided with anges 1-1 and the sides 10 are also provided with flanges 15 whereby the base member may be securely anchored within the concrete ridge il of the barn oor.

The clip 8 consists of a U-shaped member provided with apertures 16 through which a bolt 17 is adapted to pass to secure said clip to the stanchion 9 and is also provided with an aperture 18 extending centrally Itnhrough the transverse portion of said mem- The means for connecting the clip 8 to the member 7 comprises an eyed member 19 secured to the clip, a rod 2O secured to the member 7 and to said member 19 and resilient means interposed between the member 19 and the member 7. The shank 21 of the eyed member 19 passes through the aperture 18 in the clip 8 and is fashioned to form a swivel connection with said clip. The rod 2O passes through apertures 22 and 23 in end webs 24 and 25 on the member 7 and through the eye of the member 19 and is secured to the base member 7 by a pin 26 passing through it and the web 25. The resilient means interposed between the members 19 and-7 consists of coiled springs 27 surrounding the rod 20, the ends of said springs bearing against the eyed portion of the member 19 and the end webs of the member 7. Thus the stanchion is free to rotate upon the eyed member 19 and is capable of limited lengthwise movement with respect to the sides of the stall through sliding connection of said member 19 with the rod 20, the movement of said member being resisted in either direction by the springs 27. 1t will be noted that springs 27, acting upon the connection, have a constant tendency to return it and the stanchion to the normal position, indicated in Fig. 2. The disposition of the sliding eyed member adjacent the upper portion of the bottom 12 results in said member pushing any material which may lodge in the base member, outwardly owing to its sliding movement on the rod 20. It may also be noted that both of the springs may be arranged together on the rod on either side of the eyed member where such an arrangement is desired.

The invention thus exemplifies a device for securing the lower end of the stanchion to the stall floor which is simple and well adapted for the purpose described.

The invention is not to be restricted to the details of construction herein set forth, but the construction may be varied so long as it is within the scope of the appended claims.

What I claim as my invention is 1. The combination, with a stanchion and Y ber,

ber, a connection secured to the lower end of the etenehion and slidably mounted on said rod, and resilient means for maintaining said connection in normal position on said rod.

The combination, with a stanchion andY the stall door, of a device for connecting the lower end of the stunchion to the floor of the stall comprising a base member, a transversely extending rod secured to said mema clip secured to the stanchion,V an

3. The combination, with e stanchion and the stall floor, of e device for connecting Jche i lower end of the stanchion to the floor of Ythe stall comprising an open box-like. base member having upwardly converging bottom portions, und a sliding connection be-V tween the stanchion and said base' member.

In testimony whereof, I ailix my signature, in presence of two witnesses.
